How to force Typesafe Activator to listen 0.0.0.0:

Question

I recently installed Typesafe Activator to a VM. Applications created by activator can be accessed after port forwarding, but Activator seems to listen localhost. How to change this to WAN?

Answer 1

It looks like setting system properties http.address and http.port will now do this job, e.g.

./activator -Dhttp.address=0.0.0.0 -Dhttp.port=80 

Would launch Activator on a WAN on port 80 (assuming matching permissions, etc).

Answer 2

It is hardcoded right now and there's no way to change short of recompiling from source. https://github.com/typesafehub/activator/blob/master/ui/app/activator/UIMain.scala#L99

Maybe we could prefix this with if (System.getProperty("http.address") == null) File an issue on github?

Update: this is now fixed so that -Dhttp.address works (and above source link no longer goes to the right place)

Answer 3

Base on Michael Nash's answer, but should be

./activator ui -Dhttp.address=0.0.0.0 -Dhttp.port=80

for version 1.2.10
